PILE REINFORCEMENT DEVICE AND CONSTRUCTION METHOD USING PILE REINFORCEMENT DEVICE

摘要

The present invention relates to a pile reinforcing device and a construction method using the same. The construction method using the pile reinforcing device includes: a step (S10) of drilling a hole in the ground; a step (S11) of injecting a pile into the hole and injecting mortar (121); a step of compacting the ground within a predetermined radius (d2) around the pile using the pile reinforcing device; a step (S13) of injecting a hardening agent into the compact ground; and a step (S14) of hardening the hardening agent. The construction method using the pile reinforcing device is capable of improving and reinforcing all parts around the pile without a part not improved when using an existing method and ultimately maintaining bearing capacities of the reinforced ground and the pile to be always constant.
